Anesthesia practice in the 21st century is increasingly outcomes-oriented and evidence-based, but there remain significant gaps in our knowledge, even for commonly-encountered clinical situations. Currently, the two most commonly used drugs used for maintenance of anesthesia in cardiac surgical patients are isoflurane and sevoflurane. There is a belief among many cardiac anesthesiologists that sevoflurane is a better cardiac anesthetic than isoflurane, but there is very little data to support this notion. In fact, very little is known about their comparative effects on important patient outcomes because there has not been a large head-to-head prospective randomized clinical trial. This project will supply the data necessary to critically compare the two anesthetics.
The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.
This study sought to investigate safety and efficacy of biolimus-eluting stents (BES) with biodegradable polymer as compared with everolimus-eluting stents (EES) with durable polymer through 3 years of follow-up.
The purpose of the ISCHEMIA trial is to determine the best management strategy for higher-risk patients with stable ischemic heart disease (SIHD). This is a multicenter randomized controlled trial with 5179 randomized participants with moderate or severe ischemia on stress testing. A blinded coronary computed tomography angiogram (CCTA) was performed in most participants with eGFR ≥60 mL/min/1.73m2 to identify and exclude participants with either significant unprotected left main disease (≥50% stenosis) or those without obstructive CAD (<50% stenosis in all major coronary arteries). Of 8518 participants enrolled, those that had insufficient ischemia, ineligible anatomy demonstrated on CCTA or another exclusion criterion, did not go on to randomization. Eligible participants were then assigned at random to a routine invasive strategy (INV) with cardiac catheterization followed by revascularization, if feasible, plus optimal medical therapy (OMT) or to a conservative strategy (CON) of OMT, with cardiac catheterization and revascularization reserved for those who fail OMT. SPECIFIC AIMS A. Primary Aim The primary aim of the ISCHEMIA trial is to determine whether an initial invasive strategy of cardiac catheterization followed by optimal revascularization, if feasible, in addition to OMT, will reduce the primary composite endpoint of cardiovascular death, nonfatal myocardial infarction, resuscitated cardiac arrest, or hospitalization for unstable angina or heart failure in participants with SIHD and moderate or severe ischemia over an average follow-up of approximately 3.5 years compared with an initial conservative strategy of OMT alone with catheterization reserved for failure of OMT. B. Secondary Aims Secondary aims are to determine whether an initial invasive strategy compared to a conservative strategy will improve: 1) the composite of CV death or MI; 2) angina symptoms and quality of life, as assessed by the Seattle Angina Questionnaire; 3) all-cause mortality; 4) net clinical benefit assessed by including stroke in the primary and secondary composite endpoints; and 5) individual components of the composite endpoints.

The primary objective is to establish the safety of the CO-rebreathing method for measuring total blood and plasma volume in CAD patients. The working hypothesis is that the CO-rebreathing method is safe in use with coronary artery disease patients and that it does not cause myocardial ischemia or cardiovascular damage.
Growing evidence and understanding of an inherited component to several common, chronic diseases has led to an increase in the importance of information about family health history, and the integration of this information with other risk factors for common diseases, like lifestyle risk factors. The US Preventive Services Task Force (USPSTF) recommends the use of family health history as a routine genetic screening test for common diseases, as obtaining a complete family health history is the first step to identifying patients who are in need of intervention (e.g., intensive screening, lifestyle modification, preventative therapies, genetic counseling). The importance of integrating family health history with an individual's medical record will increase as our understanding of the genome evolves because it will be more essential to put detailed personal genetic information into a clinical context. Because of limited time during a typical primary care visit, and the concerns of primary care providers (PCPs) about their self-efficacy of estimating and providing guidance about risk, PCPs frequently do not obtain a family health history or provide individualized risk assessment. These issues highlight the need to leverage technology to collect these data independent of clinic visits, yet have these data interoperate with an individual's electronic health record (EHR). Telephonic interactive voice response systems (IVRS) and self-administered web-based tools are a low-cost, sustainable way of reaching out to primary care populations, independent of a visit. We propose to develop, implement, and evaluate a patient-reported, EHR-integrated personalized risk assessment module to provide tailored disease risk and risk reduction information. The Specific Aims of the proposed project are to: Aim 1: Develop a patient-reported, EHR-integrated, personalized risk assessment module to provide tailored disease risk and risk reduction information for four common diseases (breast cancer, colorectal cancer, coronary heart disease, and type II diabetes) for the patient and his/ her PCP. Aim 2: Measure the reach and effectiveness of this integrated risk assessment module by conducting a cluster randomized controlled trial (RCT) of adult primary care patients in the Brigham and Women's Primary Care Practice-Based Research Network. Aim 3: Evaluate facilitators and barriers to the adoption and implementation of this integrated risk assessment module. This project will further our understanding of how technology can be used to fill a gap in current clinical practice by facilitating the systematic collection of family health history and lifestyle risk factor data and integrating these data with an individual's EHR to personalize care in a variety of settings and for diverse patient populations. This work will use current national data standards for interoperability, and lessons learned from this project will be exportable to healthcare settings throughout the United States.
Attenuated plaque ≥ 5mm by intravascular ultrasound(IVUS) was reported to be high risk for distal embolism in Acute coronary syndrome(ACS). The purpose of this study is to assess the effect of thrombus aspiration catheter and distal protection device (filter wire; Filtrap™) in the aforementioned subgroup of patients at high risk for distal embolism.
Coagulopathy with transfusion requirements is frequent during cardiac surgery with cardiopulmonary Bypass. Rotational thromboelastrometry (ROTEM®) is a viscoelastic whole blood point of care test used to assess the patient's coagulation status. The purpose of this study is to evaluate the feasibility of ROTEM® analysis in the presence of very high heparin concentrations as seen during cardiopulmonary bypass.
The purpose of this study is to examine the effectiveness of a Psychodynamic Motivation and Training Program (PMT) for the improvement of physical fitness in patients with stable coronary heart disease as compared to advice in exercise training or treatment as usual.
